Abstract

An automatic yarn sorting apparatus adapted to the attention of a textile spinning frame, having a series of horizontally spaced yarn exit areas, and through which the yarn normally passes downwards from the exit rollers, passing through a duct suction that leads to spinning collection devices, said apparatus including a carriage adapted to move along the aforementioned spinning frame and stop when locating classification operations adjacent to the spinning exit areas required by the same service, due to conditions of extreme cut, elements perfected to detect them and to start the above-mentioned classification operations, among which is included: Elements for the production of a first photoelectric signal, aimed at determining whether said carriage is adjacent to a spin exit zone of the aforementioned spinning frame; System products of a second photoelectric signal for locating if yarn is present within the aforementioned area closely adjacent to the exit knees of the aforementioned spinning frame; An independent input control device that is put into operation when it is forced to emit an output signal capable of initiating a sorting operation, said device having a pair of input terminals and being put into operation by the coincident reception of control input signals in each of said terminals; And related signal circuit systems, which connect together the first and second signal production systems mentioned above, and said control device for intervening such a control device when no spinning is located by the second system in question within from a spin exit zone determined by the first system.
